1. Revised Schedule for SP Pre-Production • Continued testing of first two pre-production boards over next 2 weeks • Hopefully validate SP04 layout with reworked boards • Lev leaves for PNPI • Quotes from new vendors in progress; selection this month • Submit new pre-production order for 2 boards at beginning of April to new vendor • Manufacture 2.5 weeks • Inspection 0.5 week • Assembly 3 weeks • New round of testing begins mid-May • Lev returns from PNPI • Testing should go fast if no problems (software in hand) • Complete by beginning of June D. Acosta

2. Revised Schedule for Main Production • Submit remaining production of 12 boards June 1 • Boards ready for testing August 1 • Board tests completed October 1 • Full crate tests of 12 SP’s with Muon Sorter takes 2 months, as previously requested • Therefore, full production not fully tested and available until December 2005 • However, 4 other new SP04’s available October 1 • One or more SP02’s available ~now • Critical items are mezzanine cards, TF backplanes D. Acosta

3. Mezzanine Card Supply • Four SP/MS prototype mezzanine cards made and all in use • Two for Rice MPC/MS production tests • Two for SP production tests • None currently available for Slice Tests or other integration tests at CERN • Possible that one from UF could be supplied to CERN for April • Rice needs 2 continuously? • No Track-Finder at CERN for Slice Tests until current mezzanine card production completed • Connectors must be installed, cards must be fully tested (the BGAs were installed by Conquest…) • Maybe not a problem if no tests can take place at SX5 because of infrastructure issues there for the time being D.
